DIY Magic Wand Attachments

I recently bought a much-touted Magic Wand vibe, and it is everything I was led to believe! I'd love some attachemnts, but (1) I'm on a limited budget, and (2) they are all rather short for my taste.

Any suggestions on how to make some nifter insertable attachments?

This may sound stupid but with some minor adaptations (and probably a bit of gaffer tape) a sink plunger with a rounded off handle could provide waft you seek.
